4. If motor rotation is in the proper direction then
AMP draw of the motor should be checked.
Correct motor AMP draw information is
located on the inside of the Electrical Box
Cover. If motor current is higher than rated
for the motor supplied, do not continue
operation. Re-check your wiring (refer to
the inside of the electrical box cover) and if
problems continue contact your Micro-Air
Dust Collector representative for instructions.
5. Reassemble the electrical box cover onto the
enclosure.
Units Installed Outdoors
1. The remote Start/Stop Control Enclosure
supplied with the unit is not rated for outdor
use. The Control enclosure must be mounted
indoors.
2. When the enclosure is mounted, make
connection from your supply power to
terminals L1, L2, and L3. Wire size should be
rated for motor horsepower load needed for
your application (see Figure 4).
3. When power connections have been made
refer to wiring diagrams on pages 23-25 for
wiring required between the remote Start/Stop
enclosure and the Nema 4 J-box located on the
unit.
4. When supply power hase been terminated,
reconnect the power. Momentarily turn the
unit on and off with the Start/Stop switches.
Note the rotation of the motor. Proper rotation
can be viewed at the open end of the blower
motor (Remove the motor access plate if
your unit has been supplied with a motor/
silencer shroud). The proper rotation is in the
clockwise direction.
5. If the motor rotation is in the proper
direction then AMP draw of the motor
should be checked. correct motor AMP
draw information is located on the inside of
the Electrical Box Cover. If motor current
is higher than rated for the motor supplied,
do not continue operation. Re-check your
wiring (refer to the inside of the electrical box
cover) and if problems continue contact your
Micro Air Dust Collector representative for
instructions.
6. Reassemble the electrical box cover onto the
enclosure.
Unit Operation
1. Turn the unit on via the start switch located on the
side of the electrical box.
NOTE: Some particulate may pass through the
cartridge fi lters and blower upon initial start-up. This
will end once the fi lters have been seasoned and a
power cake has formed on the fi lter. If this condition
continues to occure refer to the section “Roto-Pulse
Cleaning Timer Adjustments” to increase the period
of time between pulses.
2. once the unit is running the Roto-Pulse cleaning
system will be operational. Operation is detected
by hearing a .07-second air pulse approximately
every 5 seconds. If adjustment to timing of
pulses is desired refer to the secion “Roto-Pulse
Cleaning Timer Adjustments”.
3. Check the After-Pulse Cleaning cycle by turning
off the unit via the stop switch located on the
side of the electrical box. The unit should
continue to pulse every 5 seconds for a period of
approximately 17 minutes. If adjustment to the
after-pulse time is desired, refer to the section
labeled “After-Pulse Cleaning”.
Cartridge Cleaning Operation
The Micro Air Dust Collector is designed with the
Roto-Pulse Cleaning System to clean the cartridge
fi lters.
This system provides superior cleaning performance
using a rotating tube with pre-drilled holes (see
Figure 5). As the diaphragm valve opens, the Roto-
Pulse tube rotates while air exits the holes, thus
providing the cleaning of the cartridge.
